Abstract
Description
Technical Field
[0001] This invention relates to the field of relay assembly technology, and more specifically to a detection method for reducing the defect rate of relay components. Background Technology
[0002] Relays are commonly used devices in power systems. Currently, relays are assembled manually. However, because relays consist of many parts, and each part is not very large, it is easy to make mistakes during assembly, resulting in slow assembly speed and very low efficiency.
[0003] Existing technology, such as Chinese patent application No. 201811294674.1, published on December 21, 2018, discloses a relay assembly device, including a first workbench. The first workbench is provided with a transmission device. On both sides of the first workbench, there are respectively provided a housing feeding mechanism, an adjusting cam feeding mechanism, a push plate feeding mechanism, a paddle feeding mechanism, an adjusting button feeding mechanism, a compensating lever feeding mechanism, a manual and automatic button feeding mechanism, a compensating component feeding mechanism, a front cover feeding mechanism, and a spring and stop button feeding mechanism. The spring and stop button feeding mechanism is also connected to the unloading mechanism. This document can be used for relay assembly.
[0004] As described in the literature, the assembly device directly assembles the relay components. However, since each component of a relay is usually manufactured individually, and each part cannot perfectly meet the standard size, a certain deviation is generally reserved. In addition, the moving spring plate is usually installed in the mounting slot of the housing to achieve installation. In this way, if the size of the housing is too small and the moving spring is too large, it is easy to cause mismatch during assembly, which renders the current relay unusable and wastes resources. Furthermore, if the housing and moving spring are required to be precisely matched, a large number of housings and moving springs will be unusable, thus wasting costs. Summary of the Invention
[0005] This invention provides a detection method to reduce the defect rate of relay components. The method of this invention can detect the height of the relay housing and the moving spring, thereby determining whether the current dimensions of the relay housing and the moving spring match, and thus determining whether the next step of assembly can be carried out. This reduces the defect rate during assembly, and at the same time, non-compliant housings and moving springs can be recycled and reused, reducing costs.
[0006] To achieve the above objectives, the technical solution of the present invention is: a detection method for reducing the defect rate of relay components, implemented through a relay measuring and conveying device. The relay measuring and conveying device includes a first frame, on which a relay conveyor belt extending along the length of the first frame is provided. One or more relay placement fixtures are provided on the relay conveyor belt. A housing conveying mechanism is provided on one end of the first frame of the relay conveyor belt, and a moving spring conveying mechanism is provided on one side of the first frame of the housing conveying mechanism. The housing conveying mechanism includes a housing feeding device and a housing height detection device. The housing feeding device conveys the relay housing to the housing height detection device. After the housing height detection device detects the height of the housing, the housing conveying mechanism conveys the housing to... On the relay placement fixture on the relay conveyor belt, the moving spring conveying mechanism includes a moving spring feeding device and a moving spring height detection device. The moving spring feeding device conveys the moving spring of the relay to the moving spring height detection device. After the moving spring height detection device detects the height of the moving spring, the moving spring conveying mechanism conveys the moving spring to the relay placement fixture on the relay conveyor belt. The housing conveying mechanism synchronously conveys the housing and the moving spring to the same relay placement fixture. The housing height detection device and the moving spring height detection device are communicatively connected to the information processing center. The relay conveyor belt includes a first conveyor belt and a second conveyor belt. The relay placement fixture is provided on the first conveyor belt, and the second conveyor belt is connected to the storage equipment to be tested.
[0007] The specific steps include:
[0008] (1) The outer shell feeding device delivers the outer shell to the outer shell height detection device.
[0009] (2) The shell height detection device measures the height of the shell and sends the current shell height data to the information processing center.
[0010] (3) The moving spring feeding device conveys the moving spring to the moving spring height detection device.
[0011] (4) The moving spring height detection device measures the height of the moving spring and sends the current height data of the moving spring to the information processing center.
[0012] (6) The information processing center compares the current height data of the outer shell and the moving spring.
[0013] (7) If the current height data of the outer shell and the moving spring are within the preset deviation range, then proceed to step (9).
[0014] (8) If the current height data of the outer shell and the moving spring are not within the preset deviation range, then proceed to step (10).
[0015] (9) The housing conveying mechanism and the moving spring conveying mechanism respectively convey the current housing and moving spring to the same relay placement fixture, and then proceed to step (1) to start the conveying of the next housing and moving spring.
[0016] (10) The outer shell conveying mechanism and the moving spring conveying mechanism respectively convey the outer shell and the moving spring to the second conveyor belt; the second conveyor belt conveys the moving spring and the outer shell to the storage device to be tested, and then proceeds to step (1) to start the conveying of the next outer shell and the moving spring.
[0017] The above method involves installing a housing conveying mechanism and a moving spring conveying mechanism on the first frame to facilitate the conveying of the housing and moving spring to the relay placement fixture, thus simplifying subsequent assembly. Furthermore, by incorporating housing height detection devices and moving spring height detection devices, both connected to an information processing center, the latter transmits the height data of the housing and moving spring located within the same relay placement fixture to the information processing center. The information processing center determines whether the difference between the housing height and the moving spring height is within a pre-set deviation range, and subsequently controls the housing conveying mechanism and the moving spring conveying mechanism to convey the housing and moving spring to the relay placement fixture or to the second conveyor belt, respectively. This allows for the determination of dimensional deviations between the housing and the moving spring based on the height data, thus determining whether to proceed to the next assembly step. This ensures that the dimensions of the moving spring match the dimensions of the housing, thereby improving assembly efficiency and reducing the likelihood of defective products. For deviations in height between the moving spring and the relay housing, simply discarding them would increase costs. For example, if the height of the mounting slot on the housing is slightly greater than the thickness of the moving spring, this does not affect installation, and installation can continue. Similarly, if the height of the mounting slot is slightly less than the thickness of the moving spring, installation can still proceed. If the difference between the height of the mounting slot and the thickness of the moving spring plate is significant, the components can be recycled using a conveyor belt, further saving costs.
[0018] Furthermore, the outer casing feeding device includes an outer casing feeding module and an outer casing synchronous moving assembly. An outer casing storage area is provided on the first frame. The outer casing feeding module is disposed in the outer casing storage area and moves along the X and Y axes of the outer casing storage area. The outer casing feeding module picks up the outer casing from the outer casing storage area and places it onto the outer casing synchronous moving assembly. The outer casing synchronous moving assembly includes an outer casing feeding base, an outer casing feeding moving cylinder, an outer casing feeding base plate, an outer casing placement cylinder, an outer casing feeding pneumatic fingers, and an outer casing feeding placement table. The outer casing feeding base is disposed on the first frame. The device is equipped with a shell feeding moving cylinder, a shell feeding base plate on the piston rod of the shell feeding moving cylinder, a shell placement cylinder on the shell feeding base plate, and a shell feeding connecting plate on the shell placement cylinder. There is one or more shell feeding pneumatic fingers arranged along the length of the shell feeding connecting plate. A shell feeding placement platform is provided on one side of the shell feeding base. A transfer placement slot, a shell measuring placement slot, and a shell conveying placement slot are provided on the shell feeding placement platform. Each shell feeding pneumatic finger on the shell feeding connecting plate corresponds to the transfer placement slot, the shell measuring placement slot, and the shell conveying placement slot, respectively.
[0019] The outer casing feeding module grabs the outer casing and places it in the transfer placement slot. The outer casing feeding pneumatic finger grabs the outer casing located in the transfer placement slot. The outer casing feeding moving cylinder drives the outer casing feeding pneumatic finger to move to the position of the outer casing measuring placement slot. The outer casing feeding pneumatic finger grabs the outer casing and places it in the outer casing measuring placement slot. The outer casing height detection device grabs the outer casing in the outer casing measuring placement slot and performs detection. After the outer casing height detection device completes the detection of the outer casing, it puts the outer casing back into the outer casing measuring placement slot. The outer casing feeding pneumatic finger corresponding to the transfer placement slot and the outer casing feeding pneumatic finger corresponding to the outer casing measuring placement slot simultaneously grab the outer casing. The outer casing feeding moving cylinder drives the outer casing feeding base plate to move, moving the outer casing located in the transfer placement slot to the position of the outer casing measuring placement slot, and then moving the outer casing located in the outer casing measuring placement slot into the outer casing conveying placement slot.
[0020] The above settings, through the configuration of the housing synchronous movement component, enable the housing to be detected and transported synchronously, thereby improving the efficiency of housing detection.
[0021] Furthermore, a shell flipping conveyor is provided on the first frame on one side of the shell conveying and placement trough. The shell flipping conveyor includes a shell flipping component, a shell flipping placement platform, and a shell flipping conveyor module. The shell flipping placement platform is set on the first frame. A shell flipping component is provided on the first frame between the shell conveying and placement trough and the shell flipping placement platform. A shell flipping conveyor module is provided between the shell flipping placement platform and the relay conveyor belt. The shell flipping component grabs the shell located in the shell conveying and placement trough and flips it onto the shell flipping placement platform. The shell flipping conveyor module grabs the shell on the flipping placement platform and conveys it to the relay placement fixture on the relay conveyor belt.
[0022] The shell flipping assembly includes a shell flipping mounting frame, a shell rotating motor, and a shell flipping gripper. The shell flipping mounting frame is mounted on a first frame, the shell rotating motor is mounted on the shell flipping mounting frame, and the shell flipping gripper is mounted on the rotating shaft of the shell rotating motor. The shell flipping gripper grips the shell located in the shell conveying and placement groove.
[0023] The above setup uses a rotating motor to drive a flipping gripper to flip the outer shell, thus facilitating subsequent assembly of the outer shell.
[0024] Furthermore, the casing height detection device includes a casing height detection platform, a casing height detection component, a casing height detection conveying module, and a casing height detection adjustment assembly. The casing height detection platform is mounted on the first frame via the casing height detection adjustment assembly. The casing height detection conveying module is located between one side of the casing height detection platform and the casing measurement placement slot, and the casing height detection component is located on the other side of the casing height detection platform.
[0025] The above settings use a housing detection component to measure the height of the housing, thereby determining the current height of the housing, which facilitates subsequent comparison with the height of the moving spring.
[0026] Furthermore, the outer shell height detection and adjustment assembly includes an outer shell adjustment base, an outer shell adjustment cylinder, and an outer shell adjustment connecting plate. The outer shell adjustment base is mounted on the first frame, and the outer shell adjustment cylinder is mounted on the outer shell adjustment base. The outer shell adjustment connecting plate is mounted on the piston rod of the outer shell adjustment cylinder, and an outer shell detection rotary motor is mounted on the outer shell adjustment connecting plate. The outer shell height detection platform is mounted on the rotating shaft of the outer shell detection rotary motor.
[0027] The above settings, through the housing height detection and adjustment component, enable the housing height detection platform to be oriented by the housing adjustment cylinder, and the rotation angle of the housing height detection platform to be adjusted by the housing detection rotary motor. This facilitates the detection of the housing height from multiple directions, thereby making the detection data more accurate.
[0028] Furthermore, the moving spring feeding device includes a moving spring feeding module and a moving spring storage area. The moving spring storage area is located on one side of the first frame. The moving spring feeding module grabs the moving springs in the moving spring storage area and places them on the moving spring height detection device. The moving spring height detection device includes a moving spring height detection component and a moving spring detection placement platform. The moving springs are placed on the moving spring detection placement platform. The moving spring height detection component is located above the moving spring detection placement platform. The moving spring height detection component is located on the first frame through a moving spring detection adjustment assembly. A moving spring conveying device is provided between the moving spring detection placement platform and the relay conveyor belt.
[0029] The above settings, by including a moving spring height detection component, facilitate the measurement of the moving spring's height, thereby determining the dimensional difference between the moving spring and the outer casing.
[0030] Furthermore, the moving spring detection and adjustment assembly includes a moving spring adjustment linear motor and a moving spring adjustment bracket. The moving spring adjustment linear motor is mounted on the first frame, the moving spring adjustment bracket is mounted on the drive shaft of the moving spring adjustment linear motor, and the moving spring height detection component is mounted on the moving spring adjustment bracket.
[0031] Furthermore, the moving spring conveying device includes a moving spring flipping assembly, a moving spring conveying and placing platform, and a moving spring conveying module. The moving spring conveying and placing platform is mounted on the first frame. The moving spring flipping assembly is located between the moving spring conveying and placing platform and the moving spring detection and placing platform.

[0033] The above settings, through the configuration of the moving spring flipping assembly, enable the moving spring to be flipped, thereby facilitating subsequent assembly.
[0034] Furthermore, the relay placement fixture includes a housing placement slot for placing the housing and a moving spring placement slot for placing the moving spring. The housing conveying mechanism conveys the housing into the housing placement slot; the moving spring conveying mechanism conveys the moving spring into the moving spring placement slot.

Detailed Implementation
[0045] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0046] like Figure 1 and Figure 6As shown; a relay measuring and conveying device includes a first frame 1B, on which a relay conveyor belt 11B extending along the length of the first frame 1B is provided. One or more relay placement fixtures 12B are provided on the relay conveyor belt 11B. A housing conveying mechanism 2B is provided on one end of the first frame 1B of the relay conveyor belt 11B, and a moving spring conveying mechanism 3B is provided on one side of the first frame 1B. The housing conveying mechanism 2B includes a housing feeding device and a housing height detection device 22B. The housing feeding device conveys the housing 20B of the relay to the housing height detection device 22B. After the housing height detection device 22B detects the height of the housing 20B, the housing conveying mechanism 2B conveys the housing 20B to the relay placement fixture 12B on the relay conveyor belt 11B. The moving spring... The conveying mechanism 3B includes a moving spring feeding device (not shown in the figure) and a moving spring height detection device 32B. The moving spring feeding device conveys the moving spring 30B of the relay to the moving spring height detection device 32B. After the moving spring height detection device 32B detects the height of the moving spring 30B, the moving spring conveying mechanism 3B conveys the moving spring 30B to the relay placement fixture 12B on the relay conveyor belt 11B. The outer shell conveying mechanism 2B conveys the outer shell 20B and the moving spring 30B simultaneously to the same relay placement fixture 12B. The outer shell height detection device 22B and the moving spring height detection device 32B are communicatively connected to the information processing center (not shown in the figure). In this embodiment, the information processing center is an information processing terminal such as a CPU or PLC, which is existing technology and will not be described in detail here.
[0047] like Figure 2 As shown, the relay placement fixture 12B includes a housing placement slot 121B for housing 20B and a moving spring placement slot 122B for moving spring 30B. The housing conveying mechanism 2B conveys the housing 20B into the housing placement slot 121B; the moving spring conveying mechanism 3B conveys the moving spring 30B into the moving spring placement slot 122B. By providing the housing placement slot 121B and the moving spring placement slot 122B, it is convenient to simultaneously convey the housing 20B and the moving spring 30B into the same relay placement fixture 12B, thereby facilitating subsequent assembly.
[0048] like Figure 1 and Figure 2As shown, the relay conveyor belt 11B includes a first conveyor belt 111B and a second conveyor belt 112B. A relay placement fixture 12B is provided on the first conveyor belt 111B. The second conveyor belt 112B is connected to the storage device to be tested (not shown in the figure). In this embodiment, the storage device to be tested re-feeds the housing and the moving spring to the housing conveying mechanism and the moving spring conveying mechanism, so that the housing and moving spring that do not match each other can be re-measured and matched. This prevents the scrapping of housing and moving spring that do not meet the size requirements, thereby reducing resource consumption.
[0049] like Figure 1 and Figure 3 As shown, the outer shell feeding device includes an outer shell feeding module (not shown in the figure) and an outer shell synchronous moving assembly 21B. In this embodiment, the outer shell feeding module is a moving device driven by a motor or cylinder. A housing storage area 10B is provided on the first frame 1B. The housing feeding module is disposed on the housing storage area 10B and moves along the X and Y axes of the housing storage area 10B. The housing feeding module picks up the housing 20B from the housing storage area 10B and places it onto the housing synchronous moving assembly 21B. The housing synchronous moving assembly 21B includes a housing feeding base 211B, a housing feeding moving cylinder 212B, a housing feeding base plate 213B, a housing placement cylinder 214B, a housing feeding pneumatic finger 215B, and a housing feeding placement stage 216B. The housing feeding base 211B is disposed on the first frame 1B, and the housing feeding moving cylinder 212B is disposed on the housing feeding base 211B. The piston rod is provided with a housing feeding base plate 213B, a housing placement cylinder 214B is provided on the housing feeding base plate 213B, a housing feeding connecting plate 217B is provided on the housing placement cylinder 214B, and one or more housing feeding pneumatic fingers 215B are arranged along the length direction of the housing feeding connecting plate 217B. A housing feeding placement platform 216B is provided on one side of the housing feeding base 211B. A transfer placement groove 2161B, a housing measuring placement groove 2162B and a housing conveying placement groove 2163B are provided on the housing feeding placement platform 216B. Each housing feeding pneumatic finger 215B on the housing feeding connecting plate 217B corresponds to the transfer placement groove 2161B, the housing measuring placement groove 2162B and the housing conveying placement groove 2163B respectively.
[0050] The outer casing feeding module picks up the outer casing 20B and places it in the transfer placement slot 2161B. The outer casing feeding pneumatic finger 215B picks up the outer casing 20B located in the transfer placement slot 2161B. The outer casing feeding moving cylinder 215B drives the outer casing feeding pneumatic finger 215B to move to the position of the outer casing measuring placement slot 2162B. The outer casing feeding pneumatic finger 215B picks up the outer casing 20B and places it into the outer casing measuring placement slot 2162B. The outer casing height detection device 22B picks up the outer casing 20B in the outer casing measuring placement slot 2162B and detects it. The outer casing height detection device 22B detects the outer casing 20B. After completion, the outer casing 20B is placed back into the outer casing measurement placement slot 2162B. The outer casing feeding pneumatic fingers 215B corresponding to the transfer placement slot 2161B and the outer casing measurement placement slot 2162B simultaneously grip the outer casing 20B. The outer casing feeding moving cylinder 212B drives the outer casing feeding base plate 213B to move, moving the outer casing 20B from the transfer placement slot 2161B to the position in the outer casing measurement placement slot 2162B, and then moving the outer casing 20B from the slot in the outer casing measurement placement slot 2162B into the outer casing conveying placement slot 2163B. By setting up the outer casing synchronous moving component 21B, the detection and conveying processes of the outer casing 20B can be synchronized, thereby improving the efficiency of outer casing detection.
[0051] In this embodiment, there are two transfer placement slots 2161B and three shell feeding pneumatic fingers 215B. The shell feeding pneumatic fingers 215B correspond to the positions of the two transfer placement slots 2161B and the shell measuring placement slot 2162B. Before the synchronous feeding of shells 20B begins, the shell feeding module grabs shells 20B and places them into the two transfer placement slots 2162B. Then, the shell feeding pneumatic fingers 215B corresponding to the two transfer placement slots 2161B are activated synchronously to grab the shells 20B in the transfer placement slots 2161B. However, the shell feeding pneumatic fingers 215B corresponding to the shell measuring placement slot 2162B do not grab the shells 20B. After grabbing the shells 20B, the shell feeding moving cylinder 215B drives the shell feeding pneumatic fingers 215B to... Figure 3The housing feed pneumatic finger 215B moves one placement slot distance in the direction of the middle arrow, lowering and resetting the housing 20B. This ensures that housings are present in the second transfer placement slot 2161B and the housing measurement placement slot 2162B in the direction of the arrow, but not in the first transfer placement slot 2161B. At this point, the housing feeding module can grab the housing 20B and place it in the first transfer placement slot 2161B in the direction of the arrow. Simultaneously, the housing height detection device 22B grabs the housing measurement placement slot 2162B. The outer casing 20B is inspected. After the outer casing height detection device 22B completes the inspection of the outer casing 20B, it is placed back into the outer casing measurement placement slot 2162B. After the inspection is completed, the outer casing is synchronously conveyed. The outer casing feeding pneumatic fingers 215B corresponding to the two intermediate placement slots 2161B grasp the outer casing 20B in the intermediate placement slot 2161B, and the outer casing feeding pneumatic fingers 215B corresponding to the outer casing measurement placement slot 2162B grasp the outer casing 20B in the outer casing measurement placement slot 2162B. Figure 3 Move the housing 20B in the direction of the middle arrow by one placement slot, thereby placing the housing 20B in the housing measurement placement slot 2162B into the housing conveying placement slot 2163B, thus achieving synchronous housing conveying.
[0052] like Figure 3 and Figure 4As shown, a shell flipping conveyor 23B is provided on a first frame 1B on one side of the shell conveying and placement groove 2163B. The shell flipping conveyor 23B includes a shell flipping assembly 231B, a shell flipping placement platform 232B, and a shell flipping conveyor module (not shown in the figure). The shell flipping placement platform 232B is disposed on the first frame 1B. The shell flipping assembly 231B is provided on the first frame 1B between the shell conveying and placement groove 2163B and the shell flipping placement platform 232B. The shell flipping conveyor module is provided between the shell flipping placement platform 232B and the relay conveyor belt 11B. In this embodiment, the shell flipping conveyor module is a device that is moved by a drive device such as a motor or cylinder, for example, a robotic arm. The shell flipping assembly 231B grabs the shell 20B located in the shell conveying and placement groove 2163B and flips it onto the shell flipping placement platform 232B. The shell flipping conveyor module grabs the shell 20B on the flipping placement platform 232B and conveys it to the relay placement fixture 12B on the relay conveyor belt 11B. The shell flipping assembly 231B includes a shell flipping mounting frame 233B, a shell rotation motor 234B, and a shell flipping gripper 235B. The shell flipping mounting frame 233B is mounted on a first frame 1B. The shell rotation motor 234B is mounted on the shell flipping mounting frame 233B, and the shell flipping gripper 235B is mounted on the rotation shaft of the shell rotation motor 234B. The shell flipping gripper 235B grips the shell located in the shell conveying placement groove 2163B. The shell rotation motor drives the shell flipping gripper to flip the shell, thereby facilitating subsequent assembly of the shell. In this embodiment, the shell flipping assembly 231B and the shell conveying placement groove 2163B are located on the same axis. The shell rotation motor 234B rotates 180° to grip the shell from the shell conveying placement groove 2163B and flip it onto the flipping placement table 232B.
[0053] like Figure 5As shown, the housing height detection device 22B includes a housing height detection platform 221B, a housing height detection component 222B, a housing height detection conveying module 223B, and a housing height detection adjustment assembly 224B. The housing height detection platform 221B is mounted on the first frame 1B via the housing height detection adjustment assembly 224B. The housing height detection conveying module 223B is located between one side of the housing height detection platform 221B and the housing measurement placement slot 2162B, and the housing height detection component 222B is located on the other side of the housing height detection platform 221B. In this embodiment, the housing height detection component is a device such as a camera used to capture and process images. After capturing the image, the position of the housing frame is determined. Then, the height data is measured based on the position of the housing frame. Finally, the height data of the mounting slot on the housing is determined based on the ratio of the housing frame height data to the mounting slot. The housing height detection conveying module is a device that moves the equipment by a motor or cylinder, which is existing technology and will not be described in detail here. The height of the outer casing 20B is measured by the outer casing detection component 223B to determine the current height of the outer casing 20B, which facilitates subsequent comparison with the height of the moving spring 30B.

[0059] like Figure 7 As shown, a detection method for reducing the failure rate of relay components includes the following steps:
[0060] (1) The outer shell feeding device delivers the outer shell to the outer shell height detection device.
[0061] (2) The shell height detection device measures the height of the shell and sends the current shell height data to the information processing center.
[0062] (3) The moving spring feeding device conveys the moving spring to the moving spring height detection device.
[0063] (4) The moving spring height detection device measures the height of the moving spring and sends the current height data of the moving spring to the information processing center.
[0064] (6) The information processing center compares the current height data of the outer shell and the moving spring.
[0065] (7) If the current height data of the outer shell and the moving spring are within the preset deviation range, then proceed to step (9).
[0066] (8) If the current height data of the outer shell and the moving spring are not within the preset deviation range, then proceed to step (10).
[0067] (9) The housing conveying mechanism and the moving spring conveying mechanism respectively convey the current housing and moving spring to the same relay placement fixture, and then proceed to step (1) to start the conveying of the next housing and moving spring.
[0068] (10) The outer shell conveying mechanism and the moving spring conveying mechanism respectively convey the outer shell and the moving spring to the second conveyor belt; the second conveyor belt conveys the moving spring and the outer shell to the storage device to be tested, and then proceeds to step (1) to start the conveying of the next outer shell and the moving spring.
[0069] The working principle of this invention is as follows: A housing conveying mechanism 2B and a moving spring conveying mechanism 3B are provided on the first frame 1B to facilitate the conveying of the housing 20B and the moving spring 30B to the relay placement fixture 12B, thereby facilitating subsequent assembly. A housing height detection device 22B and a moving spring height detection device 32B are provided, and these devices are communicatively connected to an information processing center. The housing height detection devices 22B and 32B send the height data of the housing 20B and the moving spring 30B, located in the same relay placement fixture 12B, to the information processing center. The information processing center determines the height of the housing 20B... Whether the difference between the height dimension of 20B and the height dimension of the moving spring 30B is within the preset deviation range, the housing conveying mechanism 2B and the moving spring conveying mechanism 3B are controlled to convey the housing 20B and the moving spring 30B to the relay placement fixture 12B or to the second conveyor belt 112B, respectively. In this way, based on the detected height data of the housing 20B and the moving spring 30B, the dimensional deviation value between the housing 20B and the moving spring 30B can be determined to determine whether to proceed to the next assembly step. This ensures that the dimensions of the moving spring 30B match the dimensions of the housing 20B, thereby ensuring assembly efficiency and reducing the likelihood of defective products.
[0070] In another embodiment, if the height of the mounting groove of the housing is higher than the height of the moving spring, a shim of the same thickness as the deviation value can be placed on the moving spring based on the deviation value between the height of the mounting groove of the housing and the height of the moving spring. The shim can be set manually or by other conveying mechanisms.
